Heavy rainfall is forecast to develop through central parts of the coast from the Illawarra to southern parts of the Mid North Coast tomorrow, Saturday, July 2.
The heavy rain may cause minor to moderate flooding and is expected to intensify further in the new week with major flooding possible.
While heavy rainfall is expected for several days from Saturday through to Tuesday the State Emergency Services (SES) says it is difficult to predict with precision the timing and location of the heaviest rainfall and flood impacts, as the trough system expected to produce the heavy rainfall has not yet formed.
With water storages near capacity, the weather system was expected to cause flooding for the catchments listed from later Saturday.
